FEEDING MECHANISM FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 268,704, dated. December 5, 1882.

' Application filed June 20, 1882. (No model.)

. 5 useful Improvements in Feeding Mechanism for Sewing-Machines, described in this specification and the drawings thereof.

The invention consists of improvements relating to the cam and yoke of the feed mechw anism to provide for adjustment and com pensate for wear.

Figure l is a front view of a portion of a sewing-machine embracing the improvements. Fig. 2 is a side view of the improvements de- Fig. 3 is a front view of the same. Fig. at is a detail view of portions thereof.

In the form of construction shown the driving shaft A has a double cam, B, havinglobes 2o 0 P on opposite sides of the driving-shaft to give vertical and lateral motion to the vertical feed-lever C by contact at upper and lower and side points of the yoke I), which is preferably made obique, and is cut away at the 25 opposite parts, Q It and S T, leaving the bearings U V for the lobe O of the cam to raise and lower the vertical lever, and the bearings W X for the lobe P of the cam tovibrate the 7 vertical lever. For adjustment in assembling 0 the parts and for compensating for the Wear of ed as to have the set-screw in the point K of the wedge, so that both wedges can be easily.

on opposite sides of the shaft, and a feed-lever v having an oblique yoke with opposite offset bearings for each lobe, the bearings being provided with adjustable wedges, substantially as set forth.

3. The combination, in sewing mechanism, of a driving-shaft, a yoke having opposite adjustable offset-bearings, and a cam having lobes on opposite sides of the driving-shaft to operate against the bearings, substantially as set forth.

In testimony whereof I hereunto subscribe my signature, in the presence of two attesting witnesses, on the 31st day of May, 1882.
